All 28 original Castle Entrance room entries have original texture layers, tilemaps and collision codes. The disc also supplies twelve bat frames, ten zombie frames in three palettes, two candle frames, small hearts, eleven large-heart frames, twenty-two gold frames,72 subweapon poses with160 parts, a white-flash atlas, the original exchange sparkle and eight small explosion frames. Original opaque and STP pixels are separated for rendering; Canvas color arithmetic approximates PSX blending. Remaining art and dynamic effects await recovery. The original axe texture is recovered with both alternating palettes and opaque/STP masks; raw RGB555 shade rows and exact sine words feed its trail.

The manual room2 setup equips Holy Water and 20 hearts without saving; the original room5 pickup remains available. Canvas preserves original per-channel RGB555 inputs and approximates rasterization/blending. The separate green-particles.json recovers eight untextured 1x1 tiles, RGB63/240/63, the zero-width draw-mode sentinel, player+4 priority, original random offsets/upward motion and twice-decremented timer.
